Tim Ewald, COM columnist for DOC Magazine, explains how COM+ works, and then sets out specific rules intended as concrete guidelines to help developers build COM+ systems.

A new vision of money as a communication technology that creates and sustains invisible--often exclusive--communities "In an engaging and timely work, brimming with fascinating anecdotes and historical and literary references, Lana Swartz brilliantly illustrates how financial technologies are quietly transforming how we socialize and what it means to belong."--Jonathan Zittrain, author of The Future of the Internet: And How to Stop It One of the basic structures of everyday life, money is at its core a communication media. Payment systems--cash, card, app, or Bitcoin--are informational and symbolic tools that integrate us into, or exclude us from, the society that surrounds us. Examining the social politics of financial technologies, Lana Swartz reveals what's at stake when we pay. This accessible and insightful analysis comes at a moment of disruption: from "fin-tech" startups to cryptocurrencies, a variety of technologies are poised to unseat traditional financial infrastructures. Swartz explains these changes, traces their longer histories, and demonstrates their consequences. She shows just how important these invisible systems are. Getting paid and paying determines whether or not you can put food on the table. The data that payment produces is uniquely revelatory--and newly valuable. New forms of money create new forms of identity, new forms of community, and new forms of power.

This pocket guide clearly and concisely spells out what you need to do to become a HOT manager. The author's message is simple, yet powerful: Make high performance the only option; be a hands-on manager; and spend lots of time with employees spelling out expectations and clarifying standards.

This book describes the theory, algorithms, and practical implementation techniques behind transaction processing in information technology systems.

The advent of multi-core architectures and cloud-computing has brought parallel programming into the mainstream of software development. Unfortunately, writing scalable parallel programs using traditional lock-based synchronization primitives is well known to be a hard, time consuming and error-prone task, mastered by only a minority of specialized programmers. Building on the familiar abstraction of atomic transactions, Transactional Memory (TM) promises to free programmers from the complexity of conventional synchronization schemes, simplifying the development and verification of concurrent programs, enhancing code reliability, and boosting productivity. Over the last decade TM has been subject to intense research on a broad range of aspects including hardware and operating systems support, language integration, as well as algorithms and theoretical foundations. On the industrial side, the major players of the software and hardware markets have been up-front in the research and development of prototypal products providing support for TM systems. This has recently led to the introduction of hardware TM implementations on mainstream commercial microprocessors and to the integration of TM support for the world’s leading open source compiler. In such a vast inter-disciplinary domain, the Euro-TM COST Action (IC1001) has served as a catalyzer and a bridge for the various research communities looking at disparate, yet subtly interconnected, aspects of TM. This book emerged from the idea having Euro-TM experts compile recent results in the TM area in a single and consistent volume. Contributions have been carefully selected and revised to provide a broad coverage of several fundamental issues associated with the design and implementation of TM systems, including their theoretical underpinnings and algorithmic foundations, programming language integration and verification tools, hardware supports, distributed TM systems, self-tuning mechanisms, as well as lessons learnt from building complex TM-based applications.

Developers need a way to interact with all data platforms in a uniform way, and Microsoft has attempted time and again to meet this need with its Universal Data Access strategy. In developing ADO.NET, Microsoft has made their additions of support for XML and disconnected data sets easier to use. This tutorial will guide the reader through ADO.NET from the top down, showing readers the hows and whys of using ADO.NET with lots of examples they can mold into their own projects right away. It is intended to be an introduction to ADO.NET for developers with some knowledge of data access. While it will show readers how ADO.NET follows on its predecessors, it will be written to avoid repeating any remedial instruction in databases and storage theory.

This case studies book is an indispensable resource for educators, students, and practitioners of nursing. It is innovative in its application of lessons from the communication sciences to common challenges in the delivery of safe patient care. The authors apply basic tenets of human communication to the context of nursing to provide a foundation for practices that can advance the safety and quality of care. The cases, which describe "close calls" and adverse events, are organized along the continuum of healthcare delivery, providing quick access to solutions in commonly encountered care situations. Each case is accompanied by a discussion of how skillful communication can be key to preventing and recovering from errors and adverse events. Thought-provoking discussion questions and references for further reading make this book a valuable reference for nursing educators, students, and practitioners across the world.

The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach, known as transactional memory, offers an alternative, and hopefully better, way to coordinate concurrent threads. The ACI (atomicity, consistency, isolation) properties of transactions provide a foundation to ensure that concurrent reads and writes of shared data do not produce inconsistent or incorrect results. At a higher level, a computation wrapped in a transaction executes atomically - either it completes successfully and commits its result in its entirety or it aborts. In addition, isolation ensures the transaction produces the same result as if no other transactions were executing concurrently. Although transactions are not a parallel programming panacea, they shift much of the burden of synchronizing and coordinating parallel computations from a programmer to a compiler, to a language runtime system, or to hardware. The challenge for the system implementers is to build an efficient transactional memory infrastructure. This book presents an overview of the state of the art in the design and implementation of transactional memory systems, as of early spring 2010.
